WAGON-BODY.

SPECIFICATION forming part of Letters Patent No. 372,775, dated November 8, 1887.

Application filed July 15, 1887. Serial No. 244,403. (No model.)

To aZZ whom it may concern:

Be it known that I, J OSEPH STUMPF, a citi zen of the United States, residing at Austin, in the county of Travis and State of Texas, har e invented a new and useful Improvement in Extensible W'agon-Bodics, of which the following is a specification.

My invention relates to an improvement in extensible wagon-bodies; and'it consists in the construction and arrangement of the parts of the same, which will be more fully hereinafter described,and clearly pointed outin the claims.

In the accompanying drawings, wherein like letters of reference indicate similar parts in the several vievv s, Figure 1 is a perspective .view of my improved extensible wagon-body.

Fig. 2 is a bottom plan view of the said body, shown extended to its full length. Fig. 3 is a perspective view of the two portions of the body, shown disconnected. Fig. 4 is an end elevation of one-half of the body. Fig. 5is a detail perspective view of one of thestrap-bolts used in connection with my improvement.

A A indicate the bottom frame or sills of the inside front body, and B B the frame or sills of the outside or rear body.

0 0 represent crosssills bolted to the front body and extending beyond the sills B B, and provided withthelipironsorplatesKKon their ends, for purposes which will be more fully hereinafter set forth. The lip irons or plates K K and the cross sills or bars 0 O haveahole, 0, formed therethrough, which is adapted to be engaged by a pin or thumb-screw, c, for fastening the sills B B to the front cross-sill 0 when in a normal position, or to the rear sill C when extended.

D is a crankshaft having a toothed or' sprocket wheel, E, mounted in connection with the central portion, and with handles or cranks G G, which may either be madeintegrally with the shaft D or with sockets, so as. to be removed, or a common wrench can be used in their stead, if so desired.

H H represent two hanger journal-boxes, which are bolted to the side sills, B B, and in which the crank-shaft D is journaled.

F indicates a square linked or jointed chain of the usual form of chain belt, which is secured at one of its ends to the cross-sill O, and passes over and in contact with the bracketengaging the chain F when the crankshaft is i turned by the operator.

It will be seen that the bottom boards, S,

cover the entire body of the front body portion and run crosswise, as shown, while only one-half of the rear body is floored by the boards 6, which run lengthwise, the said boards 6 being arranged lower than the boards S, and thus pass under the latter when the body is drawn together.

In order that the parts may readily slide one upon the other, openings to are formed in the rear portion of the rear body, which are adapted to be closed by the sliding panels W V, secured on the under side of the said body.

T represents the side panels, which are screwed to the sills A in the well-known manner, and have the rail R secured on their top edges, which acts as a flange, and, in conjunction with the strap-bolts m and the lip-irons K, a way is formed in which the rear body slides when the two bodies are united, as here inbefore set forth.

In building this wagon the back gear is always fastened to the outside or rear body, while the front gear is fastened to the front or inside body. If platform-gear is used, it will be readily seen that no change in mounting thereof will be necessary; but if three'spring or other gear with a reach is used it will be necessary'to make the gear in such a manner as not to interfere with the operation of the wagon-body.

The novelty and utility of my improved device being obviously apparent and appreciable, it is unnecessary to further enlarge upon the same herein.

I also propose to make the wagon-body, as herein described, of sheet-i ron or other analogous material which will combine strength and lightness in weight.

Having thus described my invention, what I claim is- 1. In an extensible wagon-body, the combination of two sets of sills, A B, the cross-sills and the outside sills, B, of the thumb-screw a,

substantially as described.

4. The combination, with the telescoping body portions, of the transverse boards S, secured to the inner body, thelongitudinal boards 0, secured to the outer body, and the panels IV, held to and sliding beneath the boards 0, substantially as described.

5. The combination, with the telescoping body portions, of the chain F, connected to each 20 of said body portions, the shaft D, and the sprocket-wheel E, in connection with one of said body portions, substantially as described.

6. The combination, with the telescoping body portions, of the panels T, the rail R, and 25 the strap-bolts m, substantially as described.

7. The combination, with the rear body portion, of the sliding panels XV, substantially as described.

In testimony that I claim the foregoing as my 0 own I have hereto aifixed my signaturein prescnee of two Witnesses.
